test: add unit tests for ListOrgsAndRepos, CreateIssue, ListAllIssues, ListAllPullRequests

Add comprehensive unit tests using mock HTTP servers for four key
aggregation methods in the Gitea client. Tests cover correct API
integration, caching behavior, sorting, state filtering, repo
filtering, pagination, and label handling.
